Robert Irving Elliott was an American third baseman and right fielder in Major League Baseball who played most of his career with the Pittsburgh Pirates and Boston Braves. He also briefly managed and coached in the Majors. Born in San Francisco, California, the right-handed batting and throwing Elliott stood 6 feet tall and weighed 185 pounds.
Elliott contributed some of the happiest memories to the Braves' final Boston years, winning the 1947 National League Most Valuable Player Award and earning the nickname "Mr. Team." The following season, his power hitting helped lift Boston to its second National League pennant of the 20th century, the team's first in 34 years, and last before relocating to Milwaukee. He was the second Major League third baseman to have five seasons of 100 runs batted in, joining Pie Traynor, and retired with the highest career slugging average of any NL third baseman. He also led the National League in assists three times and in putouts and double plays twice each, and ended his career among the NL leaders in games, assists, total chances and double plays at third base.
